The left and right sides of the rear side of the front plate 21 are respectively movably connected with nozzle retracting and extending mechanisms 26, and the inner tops of the two nozzle retracting and extending mechanisms 26 are fixedly connected with a retracting and extending control frame 27. The two nozzle retracting and extending mechanisms 26 each include a plurality of nozzle connecting plates 261, and the tops and bottoms of the inner walls of the two groups of nozzle connecting plates 261 are slidably connected to the outer walls of the two slide bars 25. The tops of the two outer nozzle connecting plates 261 are fixedly connected with push-pull blocks 264, and the middle parts of the rear sides of the inner and outer nozzle connecting plates 261 are rotatably connected with two rotating rods 262 facing opposite directions, and the four groups of rotating rods 262 are away from the nozzle connecting plates. One side of the middle of the connecting plate 261 is rotatably connected with a second rotating rod 263, the middle parts of multiple groups of second rotating rods 263 are rotatably connected to the middle parts of the remaining nozzle connecting plates 261, and one end of the multiple groups of second rotating rods 263 away from the middle of the nozzle connecting plate 261 is hinged, and the bottoms of multiple nozzle connecting plates 261 are fixedly connected with atomizing nozzles 265, and the rear sides of multiple atomizing nozzles 265 are fixedly connected with water pipes 266, and the sides of multiple water pipes 266 away from the atomizing nozzles 265 extend to the inner wall of the water tank body 31, and the retractable control frame 27 includes a retractable control block 271, and the front and rear sides of the bottom of the retractable control block 271 are respectively fixedly connected with hinge blocks 272, and the inner walls of the two hinge blocks 272 are rotatably connected to two rotating rods 273 with opposite inclinations.The front and rear two sets of rotating rods 273 are rotatably connected to the connecting block 274 at one side away from the hinge block 272.

The inner sides of the front and rear two sets of rotating rods 273 are fixedly connected to the spring 275. When it is necessary to adjust the spray range according to the range of dust, first start the motor 124. The operation of the motor 124 drives the worm 125 to rotate. The worm 125 meshes with the gear 126, so that the gear 126 rotates and meshes with the rack rod 113 on both sides of the outer wall of the column housing 112, and then drives the lifting shaft 121 to move up and down on the outer wall of the column housing 112 through the gear connecting plate 122. The movement of the lifting shaft 121 simultaneously drives the water tank 3 and the nozzle control mechanism 2 to move, thereby realizing the height adjustment of the nozzle control mechanism 2. When the nozzle control mechanism 2 is lifted and lowered by the lifting shaft 121, when the retraction and extension control block 271 on the top of the nozzle control mechanism 2 rises to fit with the pressing block 115, since the nozzle control mechanism 2 continues to rise through the lifting shaft 121, the retraction and extension control block 271 is pushed by the pressing block 115 and then presses the hinge block 272, so that the rotating rods 27 on both sides of the inner wall of the hinge block 272 3 rotates, and the push-pull block 264 is pushed to move in the opposite direction through the connecting blocks 274 on both sides, so that the nozzle connecting plate 261 in the nozzle retracting and extending mechanism 26 slides along the slide rod 25, and the nozzle is unfolded through the multiple sets of rotating rods 262 and the second rotating rod 263. The sliding of the nozzle connecting plate 261 adjusts the spraying angle and range of the atomizing nozzle 265 to meet the dust suppression requirements of different heights and areas. When the nozzle is fully unfolded, the interaction between the push-pull block 264 of the nozzle connecting plate 261 and the connecting block 274 reaches a balanced state, and the spraying range of the nozzle reaches the maximum at this time. If the nozzle needs to be retracted, it is only necessary to reversely operate the motor 124, the lifting shaft 121 descends, and the nozzle control mechanism 2 descends accordingly. The nozzle connecting plate 261 retracts under the action of the spring 275, and the nozzle is retracted to the initial state. The whole process realizes the automatic extension and height adjustment of the nozzle, ensuring the efficient and flexible use of the dust suppression device.

[0023] See also Figure 6The two water tanks 3 each include a water tank body 31, the bottoms of the two water tank bodies 31 are fixedly connected to the top of the water tank connection block 127, the outer tops of the two water tank bodies 31 are fixedly connected to a water tank cover control frame 32, the middle of the tops of the two water tank cover control frames 32 are fixedly connected to a dual-axis motor 33, the front and rear output ends of the two dual-axis motors 33 extend to the outside of the two water tank cover control frames 32 and are fixedly connected to a turntable 34, the outer sides of the left and right sets of turntables 34 are fixedly connected to a rotating rod 37, and the two water tanks 3 are fixedly connected to the outer sides of the two water tank cover control frames 32. The bottoms of the front and rear sides of the tank cover control frame 32 are rotatably connected with swing rods 35, and the two sets of swing rods 35 are provided with elliptical slide grooves 36. The outer walls of the two sets of rotating rods 37 are slidably connected to the inner walls of the elliptical slide grooves 36. The tops of the two sets of swing rods 35 are fixedly connected with cover control rods 38, and the inner sides of the two sets of cover control rods 38 are fixedly connected with cover connecting plates 39. The inner sides of the bottoms of the left and right sets of cover connecting plates 39 are fixedly connected with cover plates 310, and the bottoms of the two cover plates 310 are slidably connected to the top of the water tank body 31. When it rains, in order to facilitate the collection of rainwater for subsequent dust suppression, the dual-axis motor 33 is first started to drive the left and right turntables 34 to rotate. The rotation of the turntable 34 drives the rotating rod 37 to slide along the elliptical slide groove 36, thereby causing the swing arm 35 to swing. The swing of the swing arm 35 is transmitted to the cover connecting plate 39 through the cover control rod 38, and finally the cover 310 is opened or closed. In this way, it can be ensured that rainwater can smoothly flow into the water tank body 31 when it rains, and when dust suppression operations are required, the cover 310 can be closed to prevent the water in the water tank from being blown away or evaporated by the wind, thereby ensuring the water supply of the dust suppression device.

[0024] Working principle: when it is necessary to adjust the spray range according to the range of dust, first start the motor 124. The operation of the motor 124 drives the worm 125 to rotate. The worm 125 meshes with the gear 126, causing the gear 126 to rotate and mesh with the rack rod 113 on both sides of the outer wall of the column housing 112, and then drives the lifting shaft 121 to move up and down on the outer wall of the column housing 112 through the gear connecting plate 122. The movement of the lifting shaft 121 simultaneously drives the water tank 3 and the nozzle control mechanism 2 to move, thereby realizing the height adjustment of the nozzle control mechanism 2. When the nozzle control mechanism 2 is lifted and lowered through the lifting shaft 121, when the retraction and extension control block 271 at the top of the nozzle control mechanism 2 rises to fit with the pressing block 115, since the nozzle control mechanism 2 continues to rise through the lifting shaft 121, the retraction and extension control block 271 is pushed by the pressing block 115 and then presses the hinge block 272, so that the two sides of the inner wall of the hinge block 272 rotate The rod 273 rotates, and the push-pull block 264 is pushed to move in the opposite direction through the connecting blocks 274 on both sides, so that the nozzle connecting plate 261 in the nozzle retracting and unfolding mechanism 26 slides along the sliding rod 25, and the nozzle is unfolded through multiple sets of rotating rods 262 and the second rotating rod 263. The sliding of the nozzle connecting plate 261 adjusts the spraying angle and range of the atomizing nozzle 265 to meet the dust suppression requirements of different heights and areas. When the nozzle is fully unfolded, the interaction between the push-pull block 264 of the nozzle connecting plate 261 and the connecting block 274 reaches a balanced state, and the spraying range of the nozzle reaches the maximum at this time. If the nozzle needs to be retracted, it is only necessary to operate the motor 124 in the reverse direction, the lifting shaft 121 descends, and the nozzle control mechanism 2 descends accordingly. The nozzle connecting plate 261 retracts under the action of the spring 275, and the nozzle is retracted to the initial state. The whole process realizes the automatic extension and height adjustment of the nozzle, ensuring the efficient and flexible use of the dust suppression device. When it rains, in order to facilitate the collection of rainwater for subsequent dust suppression, the dual-axis motor 33 is first started to drive the left and right turntables 34 to rotate. The rotation of the turntable 34 drives the rotating rod 37 to slide along the elliptical slide groove 36, thereby causing the swing arm 35 to swing. The swing of the swing arm 35 is transmitted to the cover connecting plate 39 through the cover control rod 38, and finally the cover 310 is opened or closed. In this way, it can be ensured that rainwater can smoothly flow into the water tank body 31 when it rains, and when dust suppression operations are required, the cover 310 can be closed to prevent the water in the water tank from being blown away or evaporated by the wind, thereby ensuring the water supply of the dust suppression device.
